Abstract
【解決手段】固定要素の助けを借りて、互いに隣り合う(adjacent)骨片を保持するための外部固定システムで使用するための固定クランプ10は、固定要素を収容するための少なくとも2つの収容部71,72,73を有する少なくとも1つのクランプアセンブリ20,30を含む。このクランプアセンブリ20,30は少なくとも3つの収容部71,72,73を含み、少なくとも2つの収容部が、対応する寸法の固定要素100を収容するのに適した、異なる寸法を有する。この収容部71,72,73の長手軸は多角形に広がる。
【選択図】図1
Description
図1は、本発明によるクランプ10の好ましい第1の実施形態の斜視展開図を示す。クランプ10は、第1のクランプアセンブリ20及び第2のクランプアセンブリ30、及び、シャフト40からなり、シャフト40は、シャフト40の長手軸に沿った、この2つのクランプアセンブリ20,30内の穴21,31を通って配置される。シャフト40は、好ましくは、クランプアセンブリ20及び30を閉じることが可能なように構成されたロッキング要素である。シャフト40は、ワッシャ41を通って第1のジョー11に入る。シャフト40は、近位部42、直径が減少した部分43及びこれに続くねじ部49を有する。外ねじ部49は、シャフト40のヘッドを回すと下側のジョー11に対してシャフト40の長手部分が変わるように、遠位ジョー11内の相補的な内ねじにねじ込まれるようになっており、これにより、2つのクランプアセンブリ20及び30の間に設けられたばね15の力に逆らって、クランプ10全体の開閉が可能となる。前記ばね15は、好ましくは、ジョー12の対応する収容部に配置される。シャフト40の周りに設けられたばね15の代わりに、皿ばね(Belleville washer)等の異なるばね手段や、圧縮弾性固体又は発泡体を設けることもできる。クランプアセンブリ20及び30を閉めると、最終的には、ばね15の隣にあるジョーが、クランプアセンブリ20及び30の相対的な角度配向を固定する、ジョーの両方の表面に設けられた回転防止面44と接触することができる。
